Update SMTP class part II

Posted by Jean-Francois Ouellet on February 17th, 1999
Environment: Windows NT 4.0 with sp3, VC6.0

I've previously sent a article about Wes Clyburn's SMTP class. But I forgot to place the files TextPlain.cpp and TextPlain.h. Also, some people asked for a demo, so here you are.

The demo project is very easy to look. Go directly to the function - void CEMailDlg::OnButtonSend() - to see everything needed to understand how the class work. The project have been built with Windows NT 4.0 with sp3 and VC6.0. Even if you don't have this version it should also work. I've also added a makefile with everything needed to start a new project for those who don't have the Visual C++ 6.0.

The demo's code have been done really rapidly, I do not intent that's good programmation ;-)

  • some file attachements work, some do not ...

    Posted by qadddd on 11/14/2005 07:45am

    Hello, Thanks for these classes very usefull for me. But I have 3 problems : - more and more we have to give a user and password to log on smtp server, how can it be handled in these classes - mails arriving in my mailbax do not display date and time ? something missing in smtp exchange to handle this ? - my biggest problem : I send a mail with a files attached. But depending the file I attached, mail arriving in my mailbox still have the file or do not have it anymore. I follow the code till the send of body part, file is MIME encoded and sent but I don't retrieve it in the mailbox. It doesn't appear to be a random problem because when I use file "a.txt" it always works, and when I use file "b.txt" it always misses ... I try to simplify the maximum "b.txt" (it contains a simple line of usual characters) but I never succeed in retrieving it in the mail received in mail box. The mail itself is always present, only the file is missing . Any suggestion for debugging or solution will be appreciated Brgds DD

  • Embedded types other than TEXT_PLAIN

    These classes are excellent and I have enjoyed learning form these examples however, I cannot seem to get my own agent to work in the way that I want. I can use the existing classes to attach an rtf document to an email but what I really want is to embed enriched text directly into the e-mail message body.
    To that end I wrote an agent for TEXT_ENRICHED, defined that eMIMETypeCode, and kind of jammed together the AddMIMEPart member functions of CAppOctetStream and CTextPlain to get CTextEnriched::AddMIMEPart which handles encoding. Is this on the right track? No matter what I do the .rtf shows up as an attachment and never is expanded into the message body as desired.
    Anyone have constructive comments?

  • Using this source on PocketPC

    The Send() ends well (I check its return value in order to be sure), but then the Receive() gets stuck, and the application hangs.

    Did it happen to anyone on PC ? does anyone have any idea how to solve it ?

  • Forget to Unlock the critical section

    You call m_csAccess.Lock(); but you never call m_csAccess.Unlock();

    This fails in a multi-threaded application

    its name has a space in it.

    here is how i fixed it:


    in AppOctetStream.cpp find 


    sTemp.Format(_T( "Content-Disposition: attachment; filename=%s%s\r\n" ),szFName, szExt );


    change it to:


    sTemp.Format(_T( "Content-Disposition: attachment; filename=\"%s%s\"\r\n"),szFName, szExt );
